Dorp

From KeenWiki

The Droidiccus combined their robot technology with an organic alien life form to create the Dorp. It is believed that the aliens abducted and mutilated to produce these cyborgs were none other than the friendly martian Yorps. (This gives a new meaning to the term 'alien abduction'.) As well as being given an extra eye and placed under the Droidiccus' evil control, the Dorp have toxic skin and so, although friendly, are best avoided.

They are only found on Droidiccus Prime.
